HAND FIRE-EXTINGUISHER.

ESPECIPICATION forming part of Letters Patent No. 320,226, dated June16,1885.

Application filed March 11, 1885. (No model.)

To aZZ whom it may concern:

Be it known that we, OLIVER E. CoNNER and TIMOTHY E. MoNrumnA, both ofCincinnati, in the county of Hamilton and State of Ohio, have invented anew and useful Improvement in Hand Fire-Extinguishers, which improvementis fully set forth in the following specification and accompanyingdrawings, in which Figure 1 is a longitudinal central section of ourimproved hand fire-extinguisher, and Fig. 2 is an external view of theupper or forward end of the same.

The present invention relates to an improvement in handfire-extinguishers, consisting of an outer metallic tube provided at oneend with an ejecting tube or nozzle enlarging inwardly and projectingback,and having therein a plunger. Between said plunger and the nozzle avalve opening outwardly is provided to prevent the passage of the airinwardly, while a lateral opening from this inner tube is provided witha ball-valve to receive the fireextinguishing fluid within the shell.WVhen the plunger is operated rapidly back and forth, thefire-extinguishing fluid is received through this lateral valve and thenforced outwardly through the ejecting-tube, all of which will now befully set forth in detail.

In the accompanying drawings,A is an elongated metallic shell or tubehaving at the ends heads B and B, preferably segmental. Oentrally withinone of these heads we provide an ejecting tube or nozzle, 0, whichextends inward longitudinally, enlarging inwardly, forming an ejecting-tube, D. \Vithin this tube we provide a plunger, E, which extendsout centrally through the end of the tube D and head B at the oppositeend of the device from the head B,containing the nozzle 0. This plungeris provided with a handle, F, for operating the same within the tube D.The part of the tube D between the nozzle 0 and the plungerhead E isprovided with a valve operating outwardly.

Parallel with the tube D, between it and the outer shell, Anve provide asecond and smaller tube, G, having the end H opened, while the oppositeend,I, communicates with the forward end of the tube D, the outletbetween the two being provided with a ball-valve, J, held in position bymeans of cross-wires K.

\Vithin the end of the nozzle 0 we provide a plug or stopper, L, whichis slightly soldered in position, the outer part preferably formed withan eye, M, for hanging the same up. The plunger-stem E through the headB of the de vice is also slightly soldered when the plunger-head E isdown near the nozzle 0.

One of the heads B or B of the device is provided with an opening, N,having upon its outer side a metallic piece, 0, soldered thereon, forthe purpose of inserting the fluid into the device.

Vithin the shell A we provide any fluid or chemical preparation thatwill extinguish fires.

In operating the device, the stopper L is re moved by twisting it offwith the fingers, or otherwise, and then by giving the handle F of theplunger-rod E a slight twist the solder upon the said rod E isdisengaged, when the plunger may be operated back and forth, and thefluid within the shell, passing through the tube G, enters the largertube D, when it is ejected through the nozzle 0 upon the fire.

Vhen the device becomes empty and it becomes necessary to fill thesame,the cap O,sol dered upon the head B or B, is removed, and thedevice is then filled up, and after the cap 0 is soldered on is againready for operation.

By means of the eye M in the stopper L the device may be hung up, andthus be ready for instant use.

What we claim as new is- 1. In ahand fire-extinguisher, an outer shellprovided at one end with a nozzle enlarged inwardly, forming anejeetingtube provided with a plunger having inlet and outlet valves, theinlet-valve communicating with a longitudinal tube extending to theopposite end of the shell, the nozzle having astoppersoldered inposition, and the plungerrod also soldered in position, so as to bereadily detached, substantially as herein set forth.

2. In a hand fire-extinguisher, an elongated metallic shell havingsegmental heads, one of them having an opening for the purpose ofcharging the device with a fireextinguishing preparation, one end orhead provided with a nozzle enlarging inwardly and provided with a valveand plunger and a longitudinal tube, one end open and the opposite endprovided with a ball-valve communicating with the forward end of theejecting-tube, both the stopper-within the nozzle and the plunger-rodsoldered slightly, so as to be readily detachable when desired for use,substantially as here in set forth.

3. In a hand fire-extinguisher, an ejectingtube, one end provided with avalve and outwardly contracted so as to form anozzle, having therein astopper, the said tube provided with a lateral opening having aball-valve held in position by nieanso'f' 'wires communicating by meansof a small tube with the fluid at the opposite end, substantially asherein set forth.

4. The combination of a metallic shell havirg segmental heads, one ofthe said heads provided with an opening having a cap soldered thereon,with a pair of inner tubes, one

of them having therein a valve, thence contracted outwardly through thehead, forming a nozzle, the inner part of the tube provided with aplunger for ejecting the fluid, the other tube extending to the oppositeend of the shell, the two connected by means of an opening havingtherein a ball-valve, the Wholearranged as and for the purposesubstantially as herein set forth.

' In testimony that we claim the foregoing we have hereunto set ourhands, this 7 thday of March, 1885, in the presence of witnesses.
